"MC POV"
The few days after my return I relaxed in home. Though I did put my clones in training, I myself was quietly enjoying a slice of life genre days.
it seems news of uzushio arrived the konoha as well. The village was agitated by the unknown man aka Me, without any sort of identity defeated the three kage of suna, kiri and kumo onehandedly.
'It does sound absurd now that I think about it.' I thought. then suddenly realization hit me,'Shit! I made too big a mess, didn't I ? probably shouldn't have showed that much power.'
I shook my head as I thought my current situation. Not like anybody knows who I am anyway.
I stopped my reading to eavesdrop on my parents conversation. The clan meeting they attended described to them the aftermath of the war that clan leader learned in the council. He described the clan of the conditions I had given while in disguise as well as about the kage summit.
A week had passed and I now find myself bored staying in the village. There was nothing fun to do aside from sparring with my friends, the training also became quite monotonous as well.
"Maybe I should try taking my jutsu to nuclear. But it will be too flashy.
Hmm let's try doing implosion type of technique like that of a black hole."
"Nah forget it. it will make to much noise anyway. "
I thought about what I should look into and I got an idea.
"Let's make a pocket dimension. after all there is no isekai without 'Inventory' of your own."
That was the start of my new target. I took some theories of storage seals and combined those with that of hirashin. Well as we all know the storage seals are limited in capacity. though they are convenient as they reduce the load one needs to carry but slight damage to the scroll or the seal will make it obsolete.
The hirashin as it moves outside of time it makes sure I didn't age a single second while I was in transition. the pocket dimension connected to the jutsu was literally made the phyaics it's bitch.
How you ask?
well the entry point is small as the size of seal matrix but while inside the entry point becomes as big as me or something I teleport.
Though the mass of something I carry does affect me as I have to completely envelope it in my chakra, it is mostly so that the carried item doesn't gets torn my the void it will be in. The matter exposed to void breaks down into energy itself and disappears.
The exit point that was as big as me becomes similarly small outside as well as you know.
The jutsu literally makes a pingpong ball size hole in space and transport things and fixes the hole after.
The second Hokage was a genius to think up such a abstract concept.
Now I had a clear goal in mind as I began to try and combine the two concepts. the handiness of storage scroll where you can store and recollect exact item that you have in mind and the unlimited space the hirashin has that is literally in timestop.
After Five days of combined work of me and my clones, we finally have a prototype. Though it is stable, the seal matrix was keyed to a random coordinate dimension. As long as the seal is keyed to this particular dimension I can utilize it with the particular seal from any location.
The items stored gets tagged by a subseal as soon as it enters the pocket dimension. I have a information about the items sealed within pop in my head so I can just take it out anytime.
Now the finished product needs is instant execution, instant recall and also a HUD over the seal.
Just for this I made the seal floating cube in which I can take the item from any side.As it is made up of seals it will disappear after some time. the matrix was along the edges of the cube while the object stored is supposed to appear in the center of faces of the cube.
So next two days I perfected the jutsu, I added a projection seal as well as recorder seal.
The cube records the item picture and name I had already entered when sealing the item and combined with projection seal show it in the side of the cube. I also added a identification seal which makes sure the side is always faced toward me as well as prevented others from interacting with it like obito's kamui unless I key them in.
After I finished the final touches, I began to experiment with the cube. Making it appear while in different posture and body orientation, storing different materials living and nonliving. And as I expected the object returned unharmed. I can now remove the items stored just thinking about it of by interacting with the cube faces.
The living matter returned as stored even after few days completely unharmed. a sealed clone after a day had no collection of the time passed in this world and appeared as if no time had passed with him.
The. I stored objects with different temperature and they all returned with exact temperature even the thermometer was safe.
A scroll stored didn't affect the seal on both scroll and the cube. so space within space was also safe.
Most surprising was when I made my clone enter the cube. the clone appeared right after making me think it was a failure. but the clone told me he had spent a day inside and hirashin'ed to my location. This meant I could live inside the seal and with no time passing. the hirashin worked as spacetime coordinate where I can return to specific point in time the hirashin seal was placed while outside of this dimension.
To test this theory I made my clone teleport to the seal I put in Hokage tower and copy the scroll of seals. My clone appeared right after being sealed with a scroll as tall as him in tow. He reported to have arrived in vicinity of the seal while my past self was just activated the matrix.
Thank god I activated the seal while away from me.
The implication of a paradox was scary enough so I decided to add a time coordinate remotely so I can teleport to recorded coordinate instead of the time of activation of seal.
But that was for later for now I will focus on matter at hand.
The Five Kage Summit.
I had already informed the uzushio group to appear directly in the venuewith the hirashin seal which was set to iron country as expected being only country with no bijuu. I tried to sense the seal and felt the current atmosphere by the agitation of their chakra network. seeing a empty location, I changed to my masked identity and appeared on the seat but not before leaving a clone in charge.
I appeared on the chair sitting with all the people present jumping to their defence stance. I scratched the side of my cheek at the awkward situation,
" So how's the weather?" and laughed Uncaring of surrounding reaction.
